The vessels should continue on course and pass without sounding any whistle signals.
B
The vessels should exchange two blast whistle signals and pass starboard to starboard.
C
The vessels should exchange one blast whistle signals and pass starboard to starboard.
D
The vessel with the tow should initiate the whistle signals.
AI Explanation
The correct answer is A) The vessels should continue on course and pass without sounding any whistle signals. This is because when two power-driven vessels are meeting on a river and will pass at least 1/4 mile apart, no whistle signals are required. The vessels can safely pass one another without altering course or speed. The other options are incorrect because they involve unnecessary whistle signals, which are not required in this situation according to the International Regulations for Preventing Collisions at Sea (COLREGS).
